<P>
Thanks you, Lei. But, I have two web servers in cluster. Webserver may be online in any one of the servers. So I have defined www services in web servers - host1 and host2. And dont need an alert when www is online in any one of the servers.<BR>
<BR>
Is there any config to support this senario.<BR>
<BR>
Thank you<BR>
